PreScheds normally create Work Orders (WOs) on a schedule, like every month, every 3 months, every 12 months, or every X weeks. But a feature of PestaRoo that is not well known, is that a PreSched can generate an invoice (instead of a WO) on a schedule. Also, a PreSched can trigger a Work Order that is pre-excluded from creating an invoice at Route Sheet printing. This is very helpful where service are provided daily or weekly, but the customer is only invoiced once a month. So, in this example, you would use two PreScheds: one to create WOs daily (or weekly) that never create invoices, and a second one that creates only an invoice once per month but doesn’t create WOs. This type of flexibility is why PestaRoo’s PreSched system is the best on the market.
